“Positional cloning of chemically induced mutations is the rate-limiting step in forward genetic screens in Drosophila. Single-nucleotide polymorphisms (SNPs) are useful markers to locate a mutated region in the genome. Here, we provide a protocol for high-throughput, high-resolution SNP mapping that enables rapid and cost-effective positional cloning in Drosophila. In stage 1 of the protocol, we use highly multiplexed tag-array mini-sequencing assays to map mutations

to an interval of 1-2 Mb. In these assays, SNPs are genotyped by primer extension using fluorescently labeled dideoxy-nucleotides. Fluorescent primers are captured and detected LDC000067 on a microarray. In stage 2, we selectively isolate recombinants within the identified 1-2 Mb interval for fine mapping of mutations to about 50 kb. We have previously demonstrated the applicability of this protocol by mapping 14 muscle morphogenesis mutants within 4 months, which represents a significant acceleration compared with other commonly used mapping strategies that may take years.”

Knife radiosurgery (GKS) is currently used for primary or postoperative management of cavernous sinus (CS) hemangiomas. The authors describe their experience with 30 cases of CS hemangioma successfully managed with GKS.\n\nMethods. Sapitinib mw Thirty patients with CS hemangiomas, including 19 female and 11 male patients with a

mean age of Raf targets 53 years (range 19-78 years) underwent GKS at 7 facilities in Japan. Pathological entity was confirmed using surgical specimens in 17 patients, and neuroimaging diagnosis only in 13. Eight patients were asymptomatic before GKS, while 22 had ocular movement disturbances and/or optic nerve impairments. The mean tumor volume was 11.5 cm(3) (range 1.5-51.4 cm(3)). The mean dose to the tumor periphery was 13.8 Gy (range 10.0-17.0 Gy).\n\nResults. The mean follow-up period was 53 months (range 12-138 months). Among the 22 patients with symptoms prior to GKS, complete remission was achieved in 2, improvement in 13, and no change in 7. Hemifacial sensory disturbance developed following GKS in I patient. The most recent MR images showed remarkable shrinkage in 18, shrinkage in It and no change in 1 patient.\n\nConclusions. Gamma Knife radiosurgery proved to be an effective treatment strategy for managing CS hemangiomas. Given the diagnostic accuracy of recently developed neuroimaging techniques and the potentially serious bleeding associated with biopsy sampling or attempted surgical removal, the authors recommend that GKS be the primary treatment in most patients who have a clear neuroimaging diagnosis of this condition.
